Winter on Stock Wheels
I would consider the Michelin Pilot Sport A/S Plus. They are considered Ultra High Performance All Season tires and are basically the all season version of the PS/2 that comes stock on most IS-Fs. You will likely see better performance (handling, traction and steering response) from the Michelins than the Continentals in dry conditions. The DSWs are new technology and I'm not sure how they will do long term compared to the Michelins. Also, keep in mind that they too are considered Ultra High Performance All Season tires and not a true snow tire.
